Quickly undo Lion’s autocorrects
Lion gained a spelling correction feature from iOS that many people find… annoying, to be polite about it. Now, OS X has long underlined misspelled words in red while you write in almost any application. But taking a cue from its lil’ i-brother, Lion will autocorrect some words and replace the red underline with blue to highlight what it’s done.
If you’re not happy with Lion’s choice—perhaps you meant to misspell a word or you’re simply typing a word that Oxford doesn’t recognize yet—there’s no need to right-click or delete the word and try again. Simply hit ⌘-Z right after the blue underline appears to reverse OS X’s changes and keep on typing.
If you scrub left and right with two fingers in QuickTime Player on Lion, you’ll get a time-lapse mode that lets you quickly fast forward and rewind through footage. The controller turns into a speed gage so you can see how much more quickly you’re scrubbing forward and back.

Restoring your open windows and documents is a new feature of Lion called Resume. Apple wanted to make it easier for you to get right back to what you were doing the last time you quit an app or shut down your Mac. But if you don’t like the feature, you have a couple options for getting around it or taking more control of how apps resume:
- You can disable the Resume feature system-wide in the System Preferences > General pane, pictured below:

You can get in the habit of proactively closing documents and apps before you quit them or restart your Mac. In most apps, including browsers, Command-Option-W will close all open documents, windows, and tabs, but not quit the app (in Safari, it will close all tabs except the one you’re currently viewing). It’s a great way to quickly clear the slate and stop all that stuff from reopening next time. After that you can Command-Q to quit the app or leave it alone to reopen the next time you restart.
You can install a utility, such as RestoreMeNot, that gives you more control over how your Mac and apps behave with Lion’s Resume feature.
Safari Reading List maintains scroll position when exiting, re-entering

If you are in the middle of reading a long article in Safari’s new Reader feature (View > Show Reader) and exit to see the original page, you will resume at the same part of the article upon reentering the Reader view.
Selectively turn off Lion’s “Resume” feature when opening an app
Lion introduced a new iOS-like Resume feature that allows apps to reopen with all documents, windows, and settings right where you left them. But if you want to override this setting on an app-by-app basis, simply hold the Shift key when starting an app. It will open to its native ‘clean slate,’ with none of the documents or windows you had open the last time you quit the app.
Preview gained a signature annotation tool in Lion. Open Preferences and go to the new Signatures panel for simple instructions on how to add one or more signatures so you never have to print, sign, scan, and email something again.
